Chapter 10, Problem 88QAP

Interpretation Introduction

Interpretation: The temperature 105.0°C is the boiling temperature of an aqueous solution.The ionic compound M₂X is present as a solute in the solution. Mole fraction of solute is to be determined in the solution.

Concept introduction:

The mole of the fraction is determined using formulas which are shown below-

  $\Delta T_b=i\times k_b\times \text{molality}$

  $\Delta T_b=T_b-T_b°$

  $\text{Molality=}\frac{\text{moles of solute}}{\text{solvent(kg)}}$

  ${\text{Moles fraction}}_{\text{A}}\text{=}\frac{\text{moles of A}}{\text{total number of moles}}$
